Linux KDE - The BROWSE action is not supported on the current platform

Every time the application attempts to open the browser, it fails with the exception in the title. I'm running Kubuntu 18.04, and it seems that desktop integrations are not so good in the system. I've tried some different solutions found on the internet like ensuring the default browser is specified in KDE, updating all the packages, but nothing fixed the issue. StackOverflow guys advice to switch to usage of native API here https://stackoverflow.com/questions/18004150/desktop-api-is-not-support…

$ java -version
